      Uses (Picking or removing any natural material from public land is illegal)

        • Flowers attract hummingbirds and insects, especially bumblebees
        • Fruit eaten by birds
        • Native people used the hollow stems for pipe stems and used wood ashes to make a paste for tattooing

        Name Derivation

            Vines © DSchiel
          • Lonicera (lon-IS-er-a) – named in 1753 by Carl Linnaeus in honor of Johann Lonitzer, a German herbalist and physician (1499-1569) and/or his son, Adam Lonitzer, a German herbalist, physician, and botanist (1528-1586)
          • hispidula (his-PID-yoo-la) – from the Latin for “little bristly hairs”
          • Honeysuckle – refers to the sweet nectar

          Notes

            • Unlike the flowers of horticultural species, hairy honeysuckle flowers are not fragrant
            • This species tends to be evergreen in a mild climate (Ladybird 2018)
            • Have you noticed California buckeyes with distorted trunks along the lower Sylvan trail? Most likely these were made by rope-like honeysuckle vines, wrapping around the trunks and persisting as the trees grew
            • Host to the fungus-like microorganism Phytophthora ramorum, which causes Sudden Oak Death (SOD)
              • At Edgewood, the 2 species known to be susceptible to SOD are coast live oak (Quercus agrifolia var. agrifolia) and Pacific madrone saplings (Arbutus menziesii)
              • For a complete list of known hosts and host associates see USDA Risk Analysis for Phytophthora ramorum, pp.6-9
